It goes without saying that critical categories are as more or less fishy as they are less or more useful. I happen to believe that just as an excellent teacher is likely to teach well no matter what pedagogical theory he suffers from, so a gifted writer is likely to rise above what he takes to be his aesthetic principles, not to mention what others take to be his aesthetic principles. Indeed, I believe that a truly splendid specimen in whatever aesthetic mode will pull critical ideology along behind it, like an ocean liner trailing seagulls. Actual artists, actual texts, are seldom more than more or less modernist, postmodernist, formalist, symbolist, realist, surrealist, politically committed, aesthetically “pure,” “experimental,” regionalist, internationalist, what have you. The particular work ought always to take primacy over contexts and categories. On the other hand, art lives in human time and history, and general changes in its modes and materials and concerns, even when not obviously related to changes in technology, are doubtless as significant as the changes in a culture’s general attitudes, which its arts may both inspire and reflect. Some are more or less trendy and superficial, some may be indicative of more or less deep malaises, some perhaps healthy correctives of or reactions against such malaises.
From John Barth’s 1980 essay “The Literature of Replenishment.”
